Installation Notes
Installation of internal engine components like connecting rod bearings requires technical expertise and adherence to manufacturer specifications. The following is a general guide only; always refer to your engine's official service manual.
- Disconnect the battery and ensure the engine is cool.
- Drain the engine oil completely and remove the oil pan to access the engine's bottom end.
- Identify the connecting rod requiring service. Carefully remove the connecting rod cap nuts and cap.
- Remove the old bearing shells from both the connecting rod and the cap.
- Thoroughly clean the rod, cap, and crankshaft journal surfaces. Ensure they are free of oil, debris, and imperfections.
- Place the new bearing shells into the rod and cap, ensuring the locating tangs are seated correctly.
- Apply a quality engine assembly lubricant to the surface of the new bearings.
- Reinstall the connecting rod cap and tighten the nuts to the precise torque values specified in your service manual. Using a torque wrench is mandatory.
- Check bearing oil clearance using Plastigage as recommended by the engine manufacturer.
- Once all bearings are serviced, reinstall the oil pan with a new gasket, refill with new engine oil, and check for leaks upon starting.
Troubleshooting & FAQ
How do I confirm this bearing is correct for my Yanmar engine?
The most reliable method is to match the part number 719000-02800 to the one specified in your engine's service or parts manual. You can also use the compatibility table on this page to check if your specific engine model, like the 4LHA-STE or 4LH-DTE, is listed.
What are the symptoms of a bad connecting rod bearing?
Common symptoms include a persistent, rhythmic knocking or tapping sound from the engine that increases with RPM, low oil pressure, and the presence of metallic particles or flakes in the engine oil during an oil change.
Is this part compatible with industrial engines like the 3TN100E or 4TNE100?
While this bearing is primarily listed for the Yanmar 4LH and 4LHA marine series, some data sources indicate cross-compatibility with industrial models like the 3TN100E and 4TNE100. We recommend verifying the OEM part number (719000-02800) required for your specific industrial application before purchasing.
Should I replace all connecting rod bearings at once?
It is generally best practice to replace all connecting rod bearings as a complete set during an engine rebuild or if one has failed. This ensures consistent clearances, wear characteristics, and engine balance, preventing future failures.
What causes connecting rod bearings to fail?
The most common causes are oil starvation (low oil level or pressure), oil contamination (dirt, fuel, or coolant), engine overheating, improper installation (incorrect torque or clearance), and normal high-mileage wear.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
